Best Gas Mileage Convertibles for 2024

Our analysis of the convertibles with the best gas mileage ranks them based on the highest mpg and most fuel-efficient drivetrain for each vehicle.

The MINI Convertible convertible non-hybrid/electric is the most fuel-efficient convertible with an EPA rating of 32 MPG. The second-ranked Mazda MX-5 Miata RF convertible non-hybrid/electric also earns 30 MPG, while the third-ranked Mazda MX-5 Miata convertible non-hybrid/electric earns 29 MPG. When two or more vehicles have the same MPG rating they are then ranked by their overall quality score, as shown below. iSeeCars has ranked 5 convertibles based on fuel efficiency. This ranking is based on each model's highest-rated combined MPG figure to determine the best gas mileage convertibles.

The average fuel efficiency for a convertible is 28 MPG, and 3 models earn that figure or better for their highest-rated combined MPG model. A convertible with less than 28 combined MPG is below the segment average and may not be a good model for consumers seeking to reduce or manage their fuel consumption.

How We Rank These Cars

The iSeeCars "Best Gas Mileage" lists rank cars, trucks and SUVs based on the highest mpg and most fuel-efficient drivetrain for each vehicle.

Along with the Best Gas Mileage scores, the lists show additional iSeeCars scores because we believe other factors should be taken into account to find the best overall vehicle. If there is a tie in mpg between vehicles, we use the overall iSeeCars Score to break the tie.

The overall iSeeCars Score is an analysis of three factors: reliability, resale value and safety. It is calculated based on the latest research and analysis by our data science team. The data analysis comes from over 12 million new and used vehicles in our Longest-Lasting Cars and 5-Year Depreciation Studies, combined with NHTSA and IIHS Safety Ratings.

Vehicles are scored in three categories:

Reliability

The reliability score represents an analysis of iSeeCars' proprietary research on the longest-lasting vehicles.

Value Retention

The value retention score is based on our data science team's statistical analysis and prediction of 5-year depreciation from MSRP to determine which cars hold their value best, using US Bureau of Labor Statistics data to adjust for inflation.

Safety

The safety score is calculated based on the last five years of crash test ratings from the National Highway Traffic Safety Administration (NHTSA) and incorporates the latest Top Safety Pick information from the Insurance Institute for Highway Safety (IIHS).
